Does UL test to Canadian Standards?
Under our Canadian Listing program, UL can test products to the appropriate Canadian standards. If the product is found to be in compliance, UL will issue a UL Listing, Classification or Recognition Marking with a small “c” as an identifier. In addition, UL introduced a new Listing Mark, the C-UL US Listing Mark, in early 1998. This Mark indicates compliance with both Canadian and U.S. requirements. The Canada/U.S. UL Mark is optional.
